Priorities for Mediterranean marine turtle conservation and management in the face of climate change

As climate-related impacts threaten marine biodiversity globally, it is important to adjust conservation efforts to mitigate the effects of climate change. Translating scientific knowledge into practical management, however, is often complicated due to resource, economic and policy constraints, generating a knowledge-action gap. To develop potential solutions for marine turtle conservation, we explored the perceptions of key actors across 18 countries in the Mediterranean. These actors evaluated their perceived relative importance of 19 adaptation and mitigation measures that could safeguard marine turtles from climate change. Of importance, despite differences in expertise, experience and focal country, the perceptions of researchers and management practitioners largely converged with respect to prioritizing adaptation and mitigation measures. Climate change was considered to have the greatest impacts on offspring sex ratios and suitable nesting sites. The most viable adaptation/mitigation measures were considered to be reducing other pressures that act in parallel to climate change. Ecological effectiveness represented a key determinant for implementing proposed measures, followed by practical applicability, financial cost, and societal cost. This convergence in opinions across actors likely reflects long-standing initiatives in the Mediterranean region towards supporting knowledge exchange in marine turtle conservation. Our results provide important guidance on how to prioritize measures that incorporate climate change in decision-making processes related to the current and future management and protection of marine turtles at the ocean-basin scale, and could be used to guide decisions in other regions globally. Importantly, this study demonstrates a successful example of how interactive processes can be used to fill the knowledge-action gap between research and management.This work was conducted under FutureMares EU project that received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 869300.

Reviewing 15 years of research on neoliberal conservation:towards a decolonial, interdisciplinary, intersectional and community-engaged research agenda

In this paper, we undertake an extensive review of the neoliberal conservation literature with the aim to explore and substantiate the principal ways in which conservation is neoliberalized in practice as well as who has studied these processes and through which collaborative patterns. Using descriptive statistics and thematic content analysis, we explore selected characteristics of the peer-reviewed scholarship, including most commonly used concepts, methods and topics, geographical and co-authorship patterns, critical readings of key processes of neoliberalization, including commodification, privatization, dispossession, governance rescaling, governmentalities, and its engagement with the economic crisis, austerity politics, and social struggles. Our analysis shows the breadth of the literature in unraveling the unequal social, spatial and environmental impacts of neoliberal conservation policies as well as a significant degree of novelty in terms of topics and theories. Nonetheless, it also unravels some key gaps, including a limited engagement with quantitative methods and community-engaged social sciences and humanities approaches, a lack of focus on urban areas and urbanization, some important gaps in the theorization of the commodification of nature, a domination of Global North scholarship that contradicts the clear empirical focus of the field on the Global South, a limited engagement with social movements and grassroots activism, and a conspicuous lack of attention to the dynamics of class, gender and race. We conclude by identifying key directions for future research to address current gaps in the literature, and initiate a shift towards a decolonial, interdisciplinary, intersectional, community-engaged approach and an in-depth encounter with everyday practices of resistance

<i>Artemisinin</i> Loaded Cerium-Doped Nanopowders Improved In Vitro the Biomineralization in Human Periodontal Ligament Cells

Background: A promising strategy to enhance bone regeneration is the use of bioactive materials doped with metallic ions with therapeutic effects and their combination with active substances and/or drugs. The aim of the present study was to investigate the osteogenic capacity of human periodontal ligament cells (hPDLCs) in culture with artemisinin (ART)-loaded Ce-doped calcium silicate nanopowders (NPs); Methods: Mesoporous silica, calcium-doped and calcium/cerium-doped silicate NPs were synthesized via a surfactant-assisted cooperative self-assembly process. Human periodontal ligament cells (hPDLCs) were isolated and tested for their osteogenic differentiation in the presence of ART-loaded and unloaded NPs through alkaline phosphatase (ALP) activity and Alizarine red S staining, while their antioxidant capacity was also evaluated; Results: ART promoted further the osteogenic differentiation of hPDLCs in the presence of Ce-doped NPs. Higher amounts of Ce in the ART-loaded NPs inversely affected the mineral deposition process by the hPDLCs. ART and Ce in the NPs have a synergistic role controlling the redox status and reducing ROS production from the hPDLCs; Conclusions: By monitoring the Ce amount and ART concentration, mesoporous NPs with optimum properties can be developed towards bone tissue regeneration demonstrating also potential application in periodontal tissue regeneration strategies
